Ferret Epithelium, IgE, Serum
Use
This test is useful for establishing the diagnosis of an allergy to ferret epithelium. It helps define the allergen responsible for eliciting allergy signs and symptoms. The test identifies allergens responsible for allergic responses and/or anaphylactic episodes, confirms sensitization prior to beginning immunotherapy, and investigates the specificity of allergic reactions to insect venom allergens, drugs, or chemical allergens.
Special Instructions
Not provided.
Limitations
Testing for IgE antibodies is not useful in patients previously treated with immunotherapy to determine if residual clinical sensitivity exists or in patients where medical management does not depend on allergen specificity. Some individuals with clinically insignificant sensitivity might have measurable levels of IgE antibodies, requiring clinical context for interpretation. False-positive results may occur in patients with markedly elevated serum IgE due to nonspecific binding.
